JAMES C. MCCORMICK, OF DETROIT, MICHIGAN.

DOOR.

To all whom it may concern:

Specification of Letters Patent.

Patented Au 26,1913.

Application filed August 16, 1912. Serial No. 715,459.

Fig. 7 is a similar view of the bearing blocks Be it known that I, Jnarns C. MCCORMICK, carried by the lower end of the door.

citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Doors, of which the following is a specification.

My invention relates to new and useful improvements in doors and door casings and more particularly to that type of door having a cylindrical door post rotatably 1nount ed at one side of the door casing and seating partially in a vertical. groove formed .in the inner face of one of the door jambs, and the object of my invention is to provide a door of this character so mounted that it will. be impossible for any one, particularly children, to get their fingers be \tween the door and its amb.

lVith doors of the ordinary type if the key is lost while the door is locked or if the lock becomes broken with the locking bolt in active position, the door may be opened from its hinged side by removing the pintle pins of the hinges. With doors of the type in which a door post is revoluble in a grooved or otherwise recessed door jainb however, this is impossible and up to the present time the only way of opening the door was to break it down.

A further object of my invention therefore is to provide means for mounting a door of this type in such a manner that it nay be readily removed from the casing, if necessary, when locked.

With these and other objects in view, my invention will be more fully described, illustrated in the accompanying drawings, and then specificallv pointed out in the claim which is attached to and forms a part of this application.

In the drawings: Figure 1 is a front elevation, showing a door casing and door constructed in accordance with my invention; Fig. 2 is a section on the line 22 of Fig. 1, showing the manner of seating the upper pintle pin of the door in the door casing; Fig. 3 is a section on the line 33 of Fig. 2, showing still further details of the construction; Fig. 4 is a section on the line 4-4 of Fig. 1, showing the construction of the door post and grooved door jamb; Fig. 5 is a vertical section on the line 5-5 of Fig. 4, showing the manner of mounting the lower end of the door. Fig. 6 is a perspective view of the bearing blocks employed in the lintel.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The preferred embodiment of my invention includes a door casing having a door sill 10, a lintel l1, and side jambs 12 and 13, all of the usual construction with the exception that the side jamb 13 is provided in its inner edge with a vertically extending groove 14- which is arcuate in section, as best shown in Fig. 4- of the drawing.

The door, designated. as a whole by thenumeral 15, is of the usual type with the exception that it is provided with a cylindrical door post 16 extending throughout its entire height and preferably formed integrally with the door although it may be made in a separate piece and attached to the edge of the door in any suitable manner. As best shown in Fig. 4t of the drawing, this door post 16 is equal in curvature to the curvature of the groove 14; and seats partially therein. It will therefore be apparent that when the door is swung there will be absolutely no space between the door post 16 and jamb 13 and that therefore it will be absolutely impossible for any one to their fingers between thetloor and amb and thus be injured. Doors of this type have previously all been mounted by means of pintle pins extending from the upper and lower ends of the door post and seating in sockets formed in the door sill and in the lintel. hen, therefore, the door is locked and cannot be unlocked, either because of the loss of the key or because of the breaking lOf the lock, it has been impossible to open the door without either breaking down the door or breaking away the door casing. In order to avoid this diiliculty, I have provided the lower face of the lintel 11 with a recess 17 extending completely through the lintel from one side to the other and adapted to receive a pair of similarly formed, coacting bearing blocks 18 and 19. These bearing blocks may be of any suitable shape and size and are adapted when in place to completely fill the recess and their confronting inner faces are grooved as shown at 20 to form a bearing for the pintle pin 21 carried by the upper end of the door post. These blocks are provided with laterally directed ears or flanges 22 which are seated in the outer faces of the lintel and by means of these flanges and screws 28, the blocks are secured in place.

The door sill 10 is provided with a socket 2i and its upper face is preferably recessed to receive a bearing plate 25 having a bore registering with the upper end of the socket 2t,'this socket and bore being in alinementwith the aXis of the door post 16 and with the pintle pin 21. The lower portion of the door post 16 is cut-away as shown at 26 to provideaseatfor a pair of similarly formed co-acting bearing blocks 27 and 28. These blocks are preferably so formed as to correspond to and form continuations of the door post and are provided at one side with laterally directed ears 29 perforated to receive screws 30 by means of which the blocks may be secured to the door. The inner faces of these blocks are grooved as shown at 31 for the reception of a pintle pin 32, the lower end of which extends through the bearing plate 25 and into the socket 2% to form the lower hinge of the door. The grooves 31 are provided at their upper ends and adjacent their lower ends with laterally directed extensions which form seats for a keeper 3% formed integrally with the upper end of the pintle pin 32, the keeper of the pintle pin, when the latter is in active position being seated in the lowermost of these grooves, while in inactive position, it is seated in the uppermost.

In hanging a door of this type, the block 19 is preferably positioned in place in the lintel and the block 27 positioned in place upon the door. The door is then properly placed in the door casing and in closed position, its upper pintle pin 21 seating in the groove formed in the bearing block 19. The bearing block 18 is then secured in place firmly securing the upper portion of the door. The pintle pin 32 is then seated in the groove 31 of the bearing block 27 and dropped through the bearing plate and swung to seat its keeper in the lower extension 33 of the groove. The second bearing block 28 is then applied to the door and secured in place, thereby firmly securing the lower portion of the door.

From the foregoing description, it will be apparent that if it should become necessary to open the door while locked, the same could be readily removed from its casing 'from either side of the door by removing either the bearing blocks 19 and 27 or the bearing blocks 18 and 28 and by raising the pintle pin 32 out of engagement with the bearing plate 25 and socket 2 T. In order to permit the outward swinging of that side of the door bearing the door post 16, the jamb 13 is formed with face boards 35 which may be removed to release the door post from the groove of the door jamb.

From the foregoing description it will be apparent that I have provided an eX- tremely simple and eifective manner of mounting a. door of the character described and one which permits the ready removal of the door from the casing, if desired.

it will of course be understood that I do not wish in any way to limit myself to the specific details of construction shown and described as various changes may be made if desired, without in the slightest degree departing from the spirit of my invention.

Having thus described the invention, what is claimed as new is:

The combination with a door casing in cluding a lintel, a door sill, and a longitudinally grooved side jamb, of a door carrying a cylindrical door post at one side adapted to seat in the groove of said side jamb, and means for detachably securing said door post in place, said means including the provision of a socket in the door sill, co-acting bearing blocks secured to the lower portion of the door and having their inner faces provided with co-acting grooves, and a pintle pin seated in said grooves for vertical movement and adapted in lowered position to seat by one end in said socket, said blocks and pin being removable while the door is closed. 7

In testimony whereof I a'liix my signature in presence of two witnesses.
